Chitin

Adding Glucosamine to growth medium boosts chitin production in Yeast (S.C.)- http://ec.asm.org/cgi/reprint/2/5/886

Chitin synthesis Pathway (image) - [http://www.mekarn.org/msc2005-07/thesis07/latslrimage002.jpg] (Figure.1. Biosynthesis of chitin in insects. The pathway starts with trehalose, the main hemolymph sugar in most insects, and ends with the chitin polymer. The diagrammatic representation is based on previously published pathways (Kramer and Koga, 1986; Cohen, 2001).)

Chitin Precursor (UDP-N-Acetyl-Glucosamine) is used for Endotoxin (Lipid A) production - http://www.jbc.org/content/268/26/19858.long - possible safety issue - "When bacterial cells arelysed by the immune system, fragments of membrane containing lipid A are released into the circulation, causing fever, diarrhea, and possible fatal endotoxic shock (also called septic shock)." - thus spake wikipedia
